MacRumors Giveaway: Win a Luna Display Adapter to Turn Your iPad or Mac Into an Extra Screen
For this week's giveaway, we've teamed up with Astropad to offer MacRumors readers a chance to win a Luna Display adapter that's able to transform an extra Mac or iPad into a secondary display for your primary Mac.
Priced at $80, the Luna Display adapter is a small dongle that plugs into your Mac using a USB-C port (on newer Macs) or a Mini DisplayPort and when used in combination with the Luna Display software, your main Mac (or a PC) can be connected to an iPad or another Mac over WiFi, giving you a new way to take advantage of old hardware or add an extra display without having to invest in another device.
When connected, the Luna Display extends the primary Mac's display to the secondary Mac or iPad to allow the extra device to be used as a second screen, which is useful as people continue working and learning from home with makeshift office setups in 2021.
The Mac and iPad have built-in Sidecar functionality that can turn an iPad into a secondary display for a Mac without an accessory, but the Luna Display sets itself apart with the Mac-to-Mac support, which Sidecar can't do. Luna Display is also able to work with older iPads that don't support Sidecar.
In Mac-to-Mac mode, the primary Mac needs to have OS X El Capitan or later installed, while the secondary Mac can be running OS X Mountain Lion or later, so Luna Display works with machines that are quite old. For best performance, the main Mac should be a 2012 MacBook Air, MacBook Pro, Mac mini, iMac, or later, or a 2013 Mac Pro or later. As of November 2020, the Luna Display adapter has native support for M1 Macs, too.
Luna Display offers full keyboard, trackpad, and mouse support on both connected Macs in Mac-to-Mac mode, with more information on how it works available on the Luna Display website.
For iPads, the Luna Display is compatible with almost all modern iPads, including the iPad 2 or later, all iPad mini models, all iPad Pro models, and all iPad Air models, with iOS 9.1 or later as the only requirement. Performance is faster on newer iPads, but older models work well too.
For those who have PCs, there is a Luna Display adapter for Windows. The PC version of Luna Display extends your desktop from PC to iPad, allowing your devices to work interchangeably.

If you want to test sidecars bugginess yourself, just open up the sidecar preferences while connected and start checking/unchecking some of the boxes RE: Touch Bar and sidebar, it will disconnect with timeouts, at least mine does, all the time, and it has plenty of issues with sleep. God forbid you try to change the resolution while using it.
Another bonus, Luna lets you use the apple pencil as well as your finger, where sidecar forces you to use Apple Pencil.
b.) It has no problem accessing the graphics drivers because it doesn't need to. The dongle is used to simulate an external DP connection. If macOS makes a change to screw this up, then it screws up external displays for everyone.
The dongle isn't really a bluetooth/wifi adapter. Its a literal monitor and it taps straight into the GPU, where I believe sidecar is CPU rendering (don't 100% quote me on that)
Luna requires no subscription, though I use it in conjunction with Astropad standard. Astropad Studio requires the subscription.
Short of recording a demo I don't really know what I can do to show you the difference. I drew a few circles in Krita just now in both, wirelessly, and the results are subtle but clear, Luna keeps its arcs, where Sidecar has a few jagged edges and oddly reads the pressure sensitivity weirdly (thinner in certain points and larger jumps in pressure changes).
If I'm just using it at my desk, I use sidecar for the 3rd monitor (I also have a graphics display, so I don't really need to use the drawing features there), but Luna lets me turn my Mac mini into a laptop (assuming there is a plug nearby), and that your cannot beat. Though admittedly I don't know why sidecar doesn't have this feature, it seems simple enough to implement.
edit: I saw your other post, so, you know, ignore that part
